Optimally designed pure copper fins effectively disperse heat away from the CPU via heatpipes, while the high capacity 120mm fan quickly cools the heatsink for stable operation of high performance CPUs.

PWM Fan Speed Control

The PWM(Pulse Width Modulation) Fan automatically adjusts fan speed(RPM) according to the CPU’s temperature,?while the included Resistor Cable(RC33P) provides the option of reducing the input voltage for overall reduction of fan speed and noise.

ProsQuiet, great cooling performance, included thermal compound is of high quality, you CAN use high profile memory sticks with this since it clears all 4 slots.

ConsInstalling it on Intel systems can be annoying. Fits AMD chips way more easily. Make sure your PC case has enough clearance since this thing is huge.

SummaryCools my old Phenom II X4 965 BE to 45c under 100% load while overclocked to 4917mhz. Be cautious when cleaning/handling the heatsink... the fins are fairly thin so they can bend and even cut finger.

ConsWorst quality screws and tool every. Comes with the cheapest screws that strip just as easy as the tool. Had to cut my brackets off holding the heatsink. Worst install ever.

SummaryDon't buy this you will regret it once you see how bad the installation is. Also you have to take your motherboard out to install it. Heatsink works good but be prepared to get alternative screws and tools to install this. The quality of there parts are bad, both screws and Allen wrench that came with it stripped.

ProsEasy to Install on a Intel 1366 board. Good fit and don't look at the size of the box as this will fit in any regular ATX case. Putting the fan in the center makes the size compact. Ideal for Southbridge as they tend to run hot.

ConsIf you don't get cuts with the fin you are lucky. Keep the plastic cover on until you are ready to install. Takes a while to center it on top of the CPU.

SummaryThis is one of the best. Good finish. Does the job well. Depending on your case( if your CPU underside is exposed) I installed it on an existing system without dismantling.

SummaryI really like the cooler and it keeps the CPU (i7960) at a good temp. Max temp after hours of gaming so far was 47 C / 116 F. Might get a bit higher in the summer. Large cooler so make sure you know it will fit before purchasing. Fit with a bit of room to spare in my Antec DF-30 case. Happy I went with this one as i did not want to get into liquid cooling.

ConsMounting can be a little bit awkward if you don't have a huge case

SummaryIntel i7 930 b 3.8 (1.18v), I was getting high 50's idle and high 80's under load with stock cooling. The Zalman dropped my idle temps to about 38 and my cpu never goes above 65. Pretty satisfying figures, I would highly recommend this product if it is on sale (I got for $45)

ConsA little loud but in my box i got two video cards (crossfire!) with loud fans already. Who cares about loudness when you got your headphones on and gaming.

SummaryInstalled this on my intell i7 920 -- it dropped my idle temp from 58 deg C to 34. Very nice! The cooler that comes w/ the i7 920 is Micky Mouse -- those rubber nubs, never seemed to draw the heat sink tight enough to the processor.

I recommend this because its easy to install, and not as big as the other coolers that cost more money.
